Last April developers at Meiji University in Japan said they had developed a pair of chopsticks that can make food taste saltier without actually adding salt. Now the university and Kirin Holdings are using a similar technology and applying it to spoons and bowls.
This new tableware uses a simple, mild electrical current to enhance the salty flavors of food. This works by passing a specific wavelength of electricity from the surface of the utensil to the food which keys into the ions such as sodium chloride that trigger our sense of saltiness. In doing so these ions all get bunched together when they touch your tongue, for a heightened salty taste without actually adding any more salt.
Even better, this gear is boasting the ability to make foods taste 1.5 times saltier, a marked improvement over the 30-percent boost the chopstick prototypes provided. There’s not much to dislike here, except for maybe how they look according to some online comments.
